You do not have to be a rocket scientist to know that former employees should not have the access to the company’s IT infrastructure as once they used to do. Yet, you would be surprised to find out in how many cases we forget to lock the IT door after someone leaves a company this way or another.
Why? It seems that we worry much more about the contract, social security, cancellation period, and all other more important issues that IT security in these cases seems like a trivial thing. We do not have time to clean the cyber working space after our former colleagues, but we do not forget the other things.
Believe it or not, there is a higher probability that your former employee will “hack” your company than any hacker you can possibly think of on this planet. The worst thing about it is that we leave an open door. Any unauthorized access is potentially extremely dangerous for your company or business.
This includes cases, when your former employee feels nostalgic about his old company’s account or wants to do you harm because he was fired. It only takes a couple of minutes to change passwords and adjust new security settings. Yet, we miss to act accordingly. This is how our former employee becomes our future hacker.
